I always thought these Bitcoins might command a premium due to no counterparty risk and no need to give personal information to sketchy companies. Although from what I understand many bitcoin enthusiasts don't necessarily thrust the US government either...

More likely in my opinion: They might command a premium because buying them like this would be a lot less expensive than buying the same quantity on the open markets, where you would likely drive the price way up before you finished purchasing your target quantity.
